CAM – Computer Aided M Manufacturing f i y
CAM ((Computer p Aided Manufacturing) g) adalah teknologi perencanaan, pengaturan dan pengontrolan pembuatan produk dengan b bantuan t kkomputer. t
Mengurangi interaksi manusia (operator) dengan mesin kerja.

Yang bisa dilakukan dalam CAM : ◦ CAPP (Computer Aided Process Planing = persiapan pekerjaan yang dibantu dengan komputer) p ) ◦ Pemrograman NC (Numerical Control) dan pemrograman robot ◦ Pembuatan instruksi pekerjaan (peraturan kerja) ◦ Perencanaan material dan penyediaan perkakas potong dan alat-alat penjepit ◦ Dasar FMS (sistem komputer untuk pengontrolan sistem produksi yang fleksibel)
CAPP – Computer Aided P Process Pl Planning i y y

CAPP merupakan perkembangan berikutnya dari CAD/CAM CAPP men-generate t perencanaan proses produksi berdasarkan geometri dari part yang akan dibuat dibuat, jumlah produksi, dan informasi fasilitas produksi yyang g tersedia. CAPP mampu memilih tool dan fixture terbaik serta menghitung biaya dan waktu produksi

Mengapa CIM perlu Customer memiliki keinginan g dan tingkat kepuasan yang berbeda-beda y Permintaan akan produk sangat variatif dan fluktuatif y Dibutuhkan sistem produksi yang mengintegrasi teknologi baru agar mampu merespon cepat terhadap permintaan customer. y
Elements of CIM Information technology: Computer Computer, Communication, Control y Manufacturing technology: Manufacturing, Market, Management y 3Cs 3C supportt 3M 3Ms y
Elements of 3Cs Computer: IT IT, OS OS, programming language, database, artificial intelligence y Communication: communication technology LAN technology, y Control: control technology, algorithm y
Targets of CIM Developing p g high g q quality yp products with low cost y Integration and control of product design and manufacturing processes y Easy financial management y Increasing volume of sales y
Function of CIM 1) Order information and automatic scheduling through computer - dealing individual orders of various products - control of due dates - preparing production planning 2) Inventory control through JIT - minimizing raw material, WIP, inventory - utilizing bar code, RFID
3)) Statistical q quality y control - quality improvement 4) Monitoring facility, facility process - data collection for facility operating - reportt for f producing d i d defective f ti goods d - records & analysis of failing facility
5) Data collection for MIS - WIP data - shipment data - direct & indirect labor data - production control data ; defective rate operation rate, rate, rate failure rate, rate production rate - supplier record; quality quality, acomplishment - defective d f ti production d ti d data t
6) Managing MIS Data - reducing indirect cost - rapid decision making using database 7) Diagnosing failure g down time - minimizing - details of failure (problems)
8) Managing Technical Data, Document - managing S/W program - tool life data - quality data - product history - document update 9) Standard (ISO)
